How to Manage Pests
Pests in Gardens and Landscapes
Viruses can slow plant growth, but most do not seriously harm woody landscape plants. Damage is usually
noticeable only in foliage. Infected leaves may become spotted, streaked, discolored, distorted, or stunted.
The variegation or other foliage changes that viruses cause are sometimes considered to be attractive.
Identification | Life cycle
There is no cure or treatment for virus-infected plants in landscapes and generally none is
needed. Provide proper cultural care to improve plant vigor or replace infected plants if their growth
is unsatisfactory. Purchase high-quality, certified, virus-free or resistant nursery stock. Do not graft
virus-free plants unless you want to introduce the virus. Although certain viruses are spread by aphids
and other insects that suck plant juices, controlling insects is generally not a recommended method of
preventing virus infection in woody landscapes.
